Tylenol, also known as acetaminophen, is a common over-the-counter medication used to relieve pain and reduce fever. However, some people may have an increased sensitivity to Tylenol, leading to adverse reactions even at recommended dosages. Several factors can raise the risk of Tylenol sensitivity.

1. Genetic Factors: Some individuals have genetic variations that affect the way their bodies metabolize Tylenol. These genetic differences can lead to an increased risk of liver damage or other adverse reactions [1].

2. Frequent or Long-Term Use: Frequent or long-term use of Tylenol can increase the risk of sensitivity. This is because prolonged exposure to the drug can put a strain on the liver, which is responsible for metabolizing and eliminating it from the body [1].

3. Alcohol Consumption: Regular or excessive alcohol consumption can increase the risk of Tylenol sensitivity. This is because alcohol can also strain the liver, making it more difficult for the body to process and eliminate Tylenol [1].

4. Liver Disease: Individuals with liver disease or other liver problems are at a higher risk of sensitivity to Tylenol. This is because their livers may not be able to effectively metabolize and eliminate the drug, leading to potential liver damage or other adverse reactions [1].

5. Age: Both the very young and the elderly are at a higher risk of Tylenol sensitivity. This is because their livers may not be able to effectively metabolize and eliminate the drug, leading to potential liver damage or other adverse reactions [1].

6. Combination Products: Some cold and flu medications contain Tylenol in combination with other active ingredients. Consuming these products can increase the risk of Tylenol sensitivity, especially if the individual is unaware that they are already taking Tylenol [2].

In conclusion, several factors can raise the risk of Tylenol sensitivity, including genetic factors, frequent or long-term use, alcohol consumption, liver disease, age, and combination products. It is important for individuals to be aware of these risk factors and to consult with a healthcare provider before taking Tylenol or any other medication.
